As it stands, working around this is very difficult, due to the architecture of that code (and the underlying library). The page nav scrolling has been disabled in RTL. This may be revisited in the future, so it's a future fix issue.

The problematic part is
HTML:
var props = vertical ? {top: -item.position().top} : {left: -item.position().left};
I was playing with this a little and came up with this fix
HTML:
var horizontal = isRTL() ? {right: -(item.prevAll().length * item.outerWidth(true))} : {left: -item.position().left};
var props = vertical ? {top: -item.position().top} : horizontal;

The problematic part is
HTML:
var props = vertical ? {top: -item.position().top} : {left: -item.position().left};
I was playing with this a little and came up with this fix
HTML:
var horizontal = isRTL() ? {right: -(item.prevAll().length * item.outerWidth(true))} : {left: -item.position().left};
var props = vertical ? {top: -item.position().top} : horizontal;

@rellect
It will be great if your code can fix it in RTL
Where I can find this code? I searched in JS files but nothing similar

This file is included minified, this is why you can't find it.

To apply the fix you should open /js/xenforo/xenforo.js
Find
HTML:
{left:-m.position().left}
Replace with
HTML:
(a('html').attr('dir').toUpperCase()=='RTL'?{right:-(m.prevAll().length*m.outerWidth(true))}:{left:-m.position().left})
Then find
HTML:
if(XenForo.isRTL())return!1;
Remove this.

Thanks @rellect

It works but still there is a bug


This is the last page:

upload_2015-9-11_15-56-40.webp



When I click on the arrow, it shows this:

upload_2015-9-11_15-57-45.webp



I will send you the link so you can try.

It works perfectly :) Thanks @rellect for fixing this bug (y)

Hope this fix will be included in the next update @Mike
 
Result after applying the fix code :cool:
